Further, a sugar as a starting material, the chemical industrial raw material production (e.g., lactic acid fermentation, etc.) are also contemplated. Here, the biomass means the accumulation of organic matter derived from the Earth biosphere organism incorporated in substances circulatory system or organism (see JIS K 3600 1258).

Here, sugarcane currently used as alcohol starting material, but maize etc. are intended to be inherently used for food, long-term, stable to the industrial use resource these edible resources, effective food from the point of view of the life cycle, which is not preferable.

Therefore, to effectively utilize cellulosic resources such as herbaceous biomass and woody biomass considered future useful resources, it is an important issue.

Further, the cellulose resources, cellulose 38 to 50%, and hemicellulose component from 23 to 32% and varied, lignin components as not to fermentation material also differ from 15 to 22% respectively. For many object had been left industrial research, raw material is fixedly assumed disclosed technology production system considering the versatility of the raw materials at present, no yet.

For biomass hydrothermal decomposition apparatus according to an embodiment of the present invention will be described with reference to the drawings. Figure 1 is a conceptual diagram illustrating a biomass hydrothermal decomposition apparatus according to the first embodiment. As shown in FIG. 1, a hydrothermal decomposition apparatus 41A of biomass according to the present embodiment includes a biomass supply device 31 for supplying biomass material 11 under normal pressure to under pressure, in the supplied biomass material (in this embodiment, for example straw, etc.) 11, gradually while conveyed by the conveyance screw 43 in the interior of the lower end slanted apparatus main body from the side (hereinafter referred to as "apparatus main body") 42, a different upper end side of the feed point of the biomass material 11 pressurized hot water 15 is supplied into the apparatus main body 42 from the biomass material 11 and the hot compressed water 15 to hydrothermal degradation while facing contact, and transfers lignin components and hemicellulose components into the hot compressed water 15 , a hydrothermal decomposition apparatus 41A comprising separating lignin components and hemicellulose components from the biomass material 11 in biomass solids from the upper end of the main body 42 7 is for and a biomass discharger 51 to withdraw the atmospheric pressure from the pressure.

In the present embodiment, although supplying the biomass material 11 from the lower end, the present invention is not limited to this, this and may be supplied from the upper end to the contrary, At this time, pressurized hot water 15 supplied from the lower end. As the biomass feeder 31 for supplying the atmospheric pressure to under pressure, it may be mentioned pumping means, such as for example a piston pump or slurry pump.

Moreover, hydrothermal decomposition apparatus 41A, in the present embodiment, although an inclined type apparatus as shown in FIG. 1, the present invention is not limited thereto, vertical water as shown in FIG. 2 it may pyrolyzer 41B. The present invention may also be horizontal hydrothermal decomposition reactor.

Here, an inclined or vertical is brought into gas and the raw material generated in the hydrothermal decomposition reaction gas or the like is because preferably can exit rapidly from above. Further, since the extracted degradation products in pressurized hot water 15, will be in terms of extraction efficiency increases the concentration of the extract from top to bottom, which is preferable.

By providing the carrying screw 43, 1) solid-liquid conveying solids in counter-current flow is possible. 2) it is possible to solid-liquid separation in the apparatus main body 42. 3) the solid surface in the apparatus main body 42, mixing of the pressurized hot water in the solid proceeds reaction is accelerated.

Further, in the hydrothermal decomposition apparatus 41A, the reaction temperature is preferably in the range of 180 ~ 240 ° C.. More preferably preferably set to 200 ~ 230 ° C.. This is because low temperature of less than 180 ° C., small hydrothermal decomposition rate, a long degradation time is required, leading to increase in size of the device, is not preferable. Whereas in temperatures above 240 ° C., decomposition rate becomes excessive, the cellulose component increases the transition from solid to liquid side, excessive decomposition of hemicellulosic sugars is promoted, it is not preferable. Further, from the vicinity of hemicellulose components is about 140 ° C., cellulose from near about 230 ° C., although lignin components are dissolved from around 140 ° C., leaving the cellulosic solids side, and hemicellulose components and lignin components are sufficient degradation rate it is in the range of 180 ° C. ~ 240 ° C. with.

During its opposite contact, the biomass material 11 is a solid is decomposed by hot compressed water 15, so that the degradation product thereof is transferred dissolved in hot compressed water 15 side.

Further, solid-liquid ratio of the solid and the liquid is desirable because it can reduce the amount of steam warming for recovered water and hydrothermal decomposition smaller the liquid component. Here, the weight ratio of the biomass material and the hot compressed water supply, suitably differ by device configuration, for example 1: 1 to 1: 10, more preferably 1: 1 to 1: preferably 5.

According to this embodiment, the slurry flow-type reactor such as to supply to the apparatus main body previously mixed biomass material 11 and water, in order to impart fluidity of the slurry, quite a large amount of water relative to solid must be added (10-20 times by weight ratio), and biomass material 11, which is a raw material, another system and a pressurized hot water 15 to remove lignin components and hemicellulose components contained in the biomass to hydrothermal decomposition apparatus 41A in order to supply, it is possible to reduce the weight ratio of liquid to solid, thereby contributing to the improvement of the economy of the apparatus.

Also, heated the biomass material 11 in the hydrothermal decomposition apparatus can be implemented by direct heat exchange by contacting with pressurized hot water 15 in the apparatus main body 42. If necessary, it may be heated with steam or the like from the outside.

Here, the biomass feeder 31, a screw extruding mechanism 32 having a material seal mechanism biomass itself adopted, and supplies the biomass material 11 solid under normal pressure to under pressure. That is, by the extruding mechanism 32 consisting of a screw feeder 32a and a hydraulic cylinder 32b, biomass material 11 supplied to the inside is compressed to form a biomass plug 33, the biomass plug 33 itself hydrothermal decomposition apparatus and to perform a material seal for blocking pressure. Gradually pushed by the screw feeder 32a, gradually biomass is cut out from the tip portion of the hydraulic cylinder 32b, and thus to reliably supply the biomass material 11 into the apparatus main body 42.

Furthermore, biomass discharger 51, the configuration is the same as the biomass feeder 31, by the extruding mechanism consisting of a screw feeder 52a and a hydraulic cylinder 52 b, biomass solids was reacted under hydrothermal decomposition apparatus 17 There is compressed to form a biomass plug 53, and to perform a material seal for blocking the hydrothermal decomposition apparatus pressure biomass plug 53 itself. Then, in which the biomass solids 17 transitions the lignin components and hemicellulose components discharged hot water 16 from the pressure and allow the discharge to atmospheric pressure. At this time, the water that is residual from biomass plug 53 is dewatered. The dehydrated solution 54, since those containing a pressurized hot water-soluble component (lignin components and hemicellulose components), is sent to the discharged hot water 16, is separately treated with the discharged hot water 16.

Further, in the biomass extraction apparatus 51, since changes from the pressurized state to the normal pressure, the biomass solids 17 discharged becomes a be blasting, the enzymatic saccharification is the fiber is broken, after step saccharification efficiency can be improved.

Further, the biomass discharger 51 can remove one or both of depolymerized volatile enzymatic saccharification inhibitory components or ethanol fermentation inhibitory components.
